AWC principle of compression machine    

Tablet weight changes may be detected and controlled by watching compression force.

A pill press may be instrumented with a gauge that senses and reacts to compression force changes. Compression force fluctuation is that the results of slight changes in pill weights. it's traditional and expected that powder blends don't seem to be utterly uniform; this fluctuation is detected by checking pill weights throughout compression. once pill weights modification they generally trend, either increasing or decreasing in average pill weight. As pill weights increase the compression force will increase, and as pill weights decrease the compression force decreases.

As blended powders square measure being compressed there's an identical and measurable force rhythm that's detected employing a gauge. therefore we've created a loop; the quantity of force to compress is admittedly news pill weight. The controls may be started to react to the compression force changes, and change the weights at intervals a variety, or stop the press. If the quantity of force is just too a lot of, or not enough this can be directly due to pill weight, given that the press is being operated properly and every one components and elements square measure in sensible operative condition.

When exploitation associate automatic weight management device it's necessary to notice that changes to press settings like thickness, speed, force feeders, and pre-compression may be misinterpreted by the force monitor. correct steps should be followed to forestall improper operation. Then acceptable pill weight ranges square measure established in order that off weight tablets may be mechanically rejected.

Automatic Weight management is predicated on compression force. something that influences compression force can modification pill weight. beginning automatic press controls is far like setting the control on our car; you initially get going and once you're happy you lock it into cruise. identical should happen with the press; initial dig started the means you wish it then raise it to carry your point (as shut as possible).

Like cars there square measure several versions of pill press controls; not all square measure created equal and it depends on the vintage. The newer the controls the additional they link to alternative machine functions which will influence compression force whereas maintaining pill weight. What I mean is; if the machine is currently on control and also the operator decides to vary anything: speed, pre-comp, thickness, punch penetration, feeder speed, and so on….any of those changes influence compression force that the machine can interpret as a necessity to vary the load. Some machine controls acknowledge changes to a number of these functions et al. do not…again there square measure several levels and ages of controls.
